A new species of the genus Orobdella (Hirudinida: Arhynchobdellida: Gastrostomobdellidae) from Kumamoto, Japan, and a redescription of O. whitmani with the designation of the lectotype

Abstract

Orobdella whitmani has three syntype localities, Mt. Kinkazan, Gifu Pref., Mt. Kodaijiyama, Kyoto Pref. and Mt. Kimposan, Kumamoto Pref. The specimens from Mt. Kimposan can be distinguished from those from Mt. Kinkazan and Mt. Kodaijiyama by an annulation of somite XXVI, and possession of a tubular gastroporal duct. Specimens from Mt. Kimposan are described as representing a new species, Orobdella esulcata. Orobdella whitmani is redescribed with designation of a specimen from Mt. Kinkazan deposited at The University Museum, The University of Tokyo, as the lectotype. © 2010 Zoological Society of Japan.
